These are new industrial surplus. When extended, the distance between the pins measure 0.19" or 0.185" when squeezed with calipers. There is at least 3/8" of draw distance between the rubber cover (see picture).
This is for a lot of 25 of them (picture shows 50, but this is only for 25)
I have a lot of tooling listed and am happy to combine shipping to save you money.
